Kodi 17 b2 bug

Nod Hi I been using k17 for a week now and so far so good

but I noticed a bug I think but don’t know where to report it?

when playing a movie, I want to change the volume on screen. there’ s a widget on the bottom right which when mouseover brings up a pop up. then point to this pop up and it disappears before I get there DUH?

so cant change volume

if im in the wrong place pls point
